频率是每单位时间重复事件的发生数量。它是在赫兹（Hz）中测量的。
1 oct = 2 cps
1 cps = 0.5 oct
例子:
将15 八度转换为每秒循环：
15 oct = 30 cps
| 八度 | 每秒循环 |
|---|---|
| 0.01 oct | 0.02 cps |
| 0.1 oct | 0.2 cps |
| 1 oct | 2 cps |
| 2 oct | 4 cps |
| 3 oct | 6 cps |
| 5 oct | 10 cps |
| 10 oct | 20 cps |
| 20 oct | 40 cps |
| 30 oct | 60 cps |
| 40 oct | 80 cps |
| 50 oct | 100 cps |
| 60 oct | 120 cps |
| 70 oct | 140 cps |
| 80 oct | 160 cps |
| 90 oct | 180 cps |
| 100 oct | 200 cps |
| 250 oct | 500 cps |
| 500 oct | 1,000 cps |
| 750 oct | 1,500 cps |
| 1000 oct | 2,000 cps |
| 10000 oct | 20,000 cps |
| 100000 oct | 200,000 cps |
